Gaussian Splatting vs Gaussian Beam Tracing?4 answersGaussian Splatting and Gaussian Beam Tracing are two different methods used in modeling wave propagation in complex media. Gaussian Beam Tracing is a three-dimensional model that accurately calculates the sound field in subsonic moving media, taking into account the effect of medium motion and crosswind. It has been successfully applied to problems such as point source sound propagation and long-range sound propagation in atmospheres. On the other hand, Gaussian Splatting is a method used for modeling seismic wave propagation and diffraction in the subsurface with complex geological structures. It computes wave fields using the complex phase by directly solving the complex eikonal equation, and addresses the challenge of irregular boundaries near the central ray. Both methods have their own advantages and applications in different fields of study.

How is gaussian splatting different from nerf in novel view thensesis?5 answersGaussian splatting and NeRF differ in their approach to novel view synthesis. Gaussian splatting, as described in the paper by Leng et al., uses bilinear splatting to forward warp the source image and average pixels projected to the same location by the predicted depth. It also generates a valid pixel mask to ignore invalid pixels, effectively handling overlapping pixels and invalid areas in the synthesized image. On the other hand, NeRF, proposed by Gu et al., addresses the occlusion problem by distilling the knowledge of a 3D-aware conditional diffusion model (CDM) into NeRF through synthesizing and refining virtual views at test time. It further improves the virtual views using a NeRF-guided distillation algorithm. Both approaches aim to improve the quality of novel view synthesis, but they employ different techniques to handle occlusion and generate more accurate renderings.

Multiple Object Tracking (MOT) in trajectory prediction is a sophisticated computer vision task aimed at estimating and predicting the trajectories of multiple objects over time in video sequences. This task is crucial for various applications, including surveillance, autonomous driving, and service robotics, where understanding the movement and behavior of objects in a scene is essential. MOT systems strive to maintain the identity of each object across frames, despite challenges such as occlusions, fast motion, and changes in appearance or illumination. The core of MOT involves two main components: detection and data association. Detection identifies objects of interest in each frame, while data association links these detections across frames to form continuous trajectories. Advanced MOT methods have evolved to address specific challenges, such as low-resolution targets, by employing tracking compensation techniques to improve recall and reduce trajectory fragmentation. In 3D MOT, frameworks like TrajectoryFormer utilize point-cloud data and generate multiple trajectory hypotheses to recover missed detections and accurately estimate object trajectories. Recent approaches have also focused on enhancing the robustness of MOT systems in complex environments. For instance, methods have been developed to handle frequent occlusions and similar appearances among objects by integrating appearance and motion features, and by predicting future positions to maintain consistent tracking even when objects are temporarily obscured. Additionally, some systems employ a bi-directional tracking framework that relies less on detection performance, particularly useful in scenarios like satellite video tracking where object detection can be challenging. Moreover, the integration of appearance features extracted through learning-based networks and the prediction of physical locations in a unified tracking-by-detection paradigm have shown to significantly improve tracking accuracy, especially in managing identity switches and fragmentation. These advancements underscore the dynamic and evolving nature of MOT in trajectory prediction, highlighting the importance of innovative solutions to overcome the inherent challenges of tracking multiple objects in diverse and complex scenarios.What are common labeling strategies for 3D models?
